In the spirit of World Cup competition, we're holding our own tournament in search of the Better Stock Today. We're pitting 32 companies against each other and you, the reader, will determine the winner.

Sirius XM Holdings (NASDAQ:SIRI) takes on Pfizer (NYSE:PFE) for this last round-robin match-up in our search for the better stock today.

Consumer goods analyst Mike Finarelli believes Sirius XM should take the crown for one simple reason: a veritable franchise that includes exclusive content like the Howard Stern show and programming from ESPN Radio. Higher-quality content affords Sirius the ability to raise subscription prices, offsetting costs as well as increasing profit. While the company has continued to grow in the face of Internet radio, there's still plenty more growth ahead when you consider existing subscribers are only a fraction of all cars on the road. All of this points to more cash flow accelerating through the business for the benefit of shareholders. 

David Williamson, Motley Fool health care analyst, thinks Pfizer should advance to the next round because of one big reason -- it isn't afraid to think big. Pfizer has gone through a radical transformation: Gone is nutrition and animal health, and off-patent drugs may be next. Pfizer was unable to pull off a merger with AstraZeneca to dramatically lower its tax rate, but that doesn't mean its financial engineering is done. Expect Pfizer to spend the money on shareholder-friendly actions like increasing the dividend and ramping up share buybacks.
